Solution using objects!

I tried coming back and tackling this one with knowledge of objects and for...in loops and came up with this!

var html = '';
var colors = { red: 0, green: 0, blue: 0 };
var rgbColor;

function randomRgb() {
  for (let color in colors) {
    colors[color] = Math.floor(Math.random() * 256 );

for (let i = 0; i < 10; i++) {
  rgbColor = 'rgb(' + colors.red + ',' + colors.green + ',' + colors.blue + ')';
  html += '<div style="background-color:' + rgbColor + '"></div>';
